dom| data Java extracts data from any JDBC-compliant database, converts the data into a DOM object, and then formats the data into the desired form using XSL. In the previous article, we demonstrated how to programmatically extract data from a database. Now, let's talk about how to build a DOM object and format the data with an XSL style sheet. As a result, the final output is available to any application a

Xml is good, but it is not suitable for displaying data. (More query than HTML !)What the XML file makes does not look so beautiful, but you can still find a remedy.
XML can only focus on the description of data and file formats, and the display work is handed over to the typographical style sheet.Typographical style table: CSS and

Today began to seriously learn validator control, draw the following experience:
1. With regard to the use of the RegularExpressionValidator control, I used this feature first because I wanted to use this control for email verification. I started by typing: [a-za-z0-9]@ [A-za-z0-9]{1,}, but the validation always fails, prompting for errors until I enter the format of x@x (or any of the characters in the x@*--* that represent me). Understand, the origi
This article mainly introduces the ZF framework for use with the validator (custom calibrator and validator chain), need friends can refer to the following nbsp; Code as follows: ; nbsp;
The name of the regular expression validator: Regex, he checks whether the field of the checksum is matched by a regular expression
Parameters:
FieldName: This parameter specifies the name of the Action property of the checksum, and if the field checksum style is used, it is not necessary to specify the parameter; expression: Optionally, this parameter specifies a matching regular expression; Casesemsitive: Optionally, this parameter indicates that

When a rule applied to a source element is determined, the template for that rule is implemented. A template can contain the elements of a literal result, character data, and instructions that produce a tree portion of the result. Directives are represented by elements in the XSL Name field and can be processed by selecting descendant

The safe usage of validator in Yii
At the beginning of the use of Yii, has been the validation rules in the safe is not very understanding, today tested, is to understand the connotation of safe. Always think that safe is the framework of the input content filtering, such as SQL injection filter, in fact, is not, safe or unsafe is mainly in the $model->attributes=$_post[' User '; This assignment is called bulk copy (Massive Assignment) in Yii, and wh
Function Description:
1. Background check: The default value is assigned if the value is null when validating.
2. Foreground check: Check when the mouse loses focus, if there is a non-null (required) check, non-null authentication is performed first, and if null authentication is empty, the default value is automatically populated after the mouse loses focus.
How to use:
In the rules () function call $rules[] = model::addrule (' cat_sort ', ' Default ', [' value ' = ' 255 ']);

If you are not familiar with writing javascript, It is a headache to use jquery validator. To solve this problem, I wrote a c # helper for jquery validator. After using helper, you can get VS. NET Support by writing the verification program. It mainly provides the sensing function to facilitate the compilation.
If javascript is used, it is described as follows:
From the code point of view, helper is much
